Leaf Discolouration

Misanthropestarted grow question 4 years ago

I notice some leaves developing this yellow discoloration on the older growth, usually closer to the central stalk than the outside. The green gradually shifts to yellow going from mid leaf outward to the tip. I'm hoping it's just lack of sunlight from the dense foliage. Ideas?

Lack of light and nitrogen. I usually just defoliate that area anyway

Yellowing copper leaves late flower Harvest is coming up soon and I have noticed some of my leaves mostly the bottom but some on top also have started to turn yellow with brown/copper spots. I believe it is cal mag deficiency, will this mess with my yield or quality of the bud?

Early nute burn or normal?I apologize if this is a stupid question... I'm brand new What is your guys opinion on this slight discolouring in the centre of the plant. I'm not sure if this is a really really early nute burn, or if it's just a lack of Chlorophyll
